DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter unclear.

As shown in FIG. 1, an apparatus for forming an event picture when an event occurs in a mobile communication terminal according to an embodiment of the invention may comprise a picture backup module 11, a backup picture storing section 12, a picture synthesizing section 13, an event processing module 14 and a button input section 15.

The picture backup module 11 backs up a service picture currently displayed on a LCD screen of the terminal into the backup picture storing section 12 when it is notified of an event occurrence. The backup picture storing section 12 serves to temporarily store the picture backed up by the picture backup module 11.

The picture synthesizing section 13 overlaps an event picture over the backup picture stored in the backup picture storing section 12 under control of the event processing module 14 to display the event picture on the LCD screen. After displaying a final event picture, it notifies the event processing module 14 of the result. At this time, a picture synthesis transparency of the backup picture and the event picture may be changed at a periodic time with a timer so that the picture displayed on the terminal screen is gradually displayed from the backup picture to the event picture.

The event processing module 14 notifies the picture backup module 11 of an event occurrence so that the picture backup module 11 backs up a current service picture, when any event occurs in the state that the service picture is displayed on the LCD screen. At this time, the event processing module 14 controls the button input section 15 to interrupt a command input through the buttons of the terminal and transmits the event picture information to the picture synthesizing section 13 to synthesize the backup picture and the event picture. After that, when it is notified that a final event picture is displayed by the picture synthesizing section 13, the event processing module 14 controls the button input section 15 to enable the command input through the buttons again and performs a corresponding event processing.

The button input section 15 comprises a keypad and senses an operation of a number, character or function buttons used for a variety of services provided in the terminal to receive the button information. In addition, the button input section 15 serves to temporarily interrupt a command input through the buttons under control of the event processing module 14.

Hereinafter, a method for forming an event picture when an event occurs in a mobile communication terminal according to an embodiment of the invention will be specifically described with reference to FIGS. 2 and 3.

First, when a user of the terminal performs a button input operation, the button input section 15 senses the button operation and receives corresponding button information. When any event occurs such as call reception, alarm or message reception while the terminal user uses a service through the button input (S21), the event processing module 14 notifies the picture backup module 11 of the event occurrence and controls the button input section 15 to interrupt the command input through the buttons (S22).

At this time, the picture backup module 11, which is notified of the event occurrence from the event processing module 14, backs up the service picture being currently displayed on the LCD screen of the terminal in the backup picture storing section 12. For example, it is assumed that the terminal user performs a button operation and thus a picture for setting service as shown in FIG. 3B is displayed on the LCD screen. When the picture backup module 11 is notified of a call reception event occurrence from the event processing module 14 while the service picture is being displayed, the picture backup module 11 backs up and stores the picture setting service picture (in FIG. 3B), which is the current service picture, in the backup picture storing section 12 (S23).

The event processing module 14 transmits the event picture information to the picture synthesizing section 13. Thereby, the picture synthesizing section 13 overlaps the event picture over the backup picture, which is the service picture stored in the backup picture storing section 12, thereby displaying the event picture on the terminal screen (S24). At this time, a picture synthesis transparency between the backup picture (FIG. 3B) and the event picture (FIG. 3G) may be changed at a periodic time with a timer so that the event picture is gradually displayed on the LCD screen. For example, as shown in FIGS. 3B to 3G, an overlapping percent of the event ‘picture over the backup picture is changed by 20%, 40%, 60% and 80% so that the picture displayed on the LCD screen is gradually displayed into the event picture.

After that, the picture synthesizing section 13 displays a call reception notifying picture, which is a final event picture as shown in FIG. 3G, on the terminal screen and then notifies the event processing module 14 of a result of the final event picture display (S25). When the event processing module 14 is notified that the final event picture is displayed on the LCD screen, it controls the button input section 15 to cancel the interruption of the button input through the keypad, thereby enabling the button input again. Then, as certain buttons are inputted, it performs a corresponding event processing (S26).

As described above, according to the embodiments of the invention, when any event occurs while a service picture is displayed on the terminal, the event picture is overlapped over the current service picture to gradually display the event picture. Accordingly, the terminal user can correctly perceive the event occurred during the service. In addition, when the event occurs, a command input through the buttons is interrupted until a final event picture is displayed, so that it is possible to prevent an unintended erroneous operation due to an erroneous button manipulation when the event occurs.
